Planet Nine is out there, and astronomers are determined to find it, according to a new statement from NASA. ... While the mysterious world still has yet to be found, astronomers have discovered a number of strange features of our solar system that are best explained by the presence of a ninth planet, according to the NASA statement. In 2016, Batygin and co-author Mike Brown, an astronomer at Caltech, published a study that examined the elliptical orbits of six known objects in the Kuiper Belt, a distant region of icy bodies stretching from Neptune outward toward interstellar space. Their findings...

In January, astronomers revealed evidence for the potential existence of another planet in the solar system. Researchers suggest that if this world — dubbed Planet Nine — exists, it could be about 10 times Earth's mass and orbit the sun at a distance about 500 times the distance from the Earth to the sun. Previous research suggested that Planet Nine would possess a highly tilted orbit compared with the relatively thin, flat zone in which the eight official planets circle the sun. This led scientists to investigate whether Planet Nine's slant might help explain other tilting seen elsewhere in the...

In January, researchers at Caltech in the US suggested a large, additional planet might be lurking in the icy outer reaches of the Solar System. Now, a team at the University of Bern in Switzerland has worked out what they say are upper and lower limits on how big, bright and cold it might be. The study has been accepted by the journal Astronomy and Astrophysics. Prof Mike Brown and Dr Konstantin Batygin made their case for the existence of a ninth planet in our Solar System orbiting far beyond even the dwarf world Pluto. There are no direct observations...

A mysterious planet that wiped out life on Earth millions of years ago could do it again, according to a top space scientist. And some believe the apocalyptic event could happen as early as this month. Planet Nine — a new planet discovered at the edge of the solar system in January — has triggered comet showers that bomb the Earth’s surface, killing all life, says Daniel Whitmire, of the University of Louisiana. The astrophysicist says the planet has a 20,000-year orbit around the sun and, at its closest to us, it knocks asteroids and comets toward Earth. Fossil evidence...

And this new planet could be huge. Back in January, the astronomer who led the charge to have Pluto demoted to dwarf planet status announced that he’d just found evidence that a huge, icy planet could be lurking on the edge of the Solar System, just past Neptune. Mike Brown, a planetary astronomer at Caltech University, estimated that the hypothetical 'Planet Nine' appears to be circling the Sun on a super-elongated orbit that takes an incredible 10,000 to 20,000 years to complete. And now, thanks to a newly detected Kuiper Belt Object (KBO) that’s acting really strange, Brown says the...

Planet Nine - a newly proposed but not yet confirmed world perhaps 10 times more massive than Earth that's thought to orbit far beyond Pluto — probably could not have triggered such "death from the skies" events, researchers said. Planet Nine likely has an elliptical orbit, coming within 200 to 300 astronomical units (AU) of the sun at its closest approach and getting as far away as 600 to 1,200 AU, Brown said. (One AU is the distance from Earth to the sun - about 93 million miles, or 150 million kilometers). Neptune orbits about 30 AU from the sun,...
